Deep market expertise, real-world accuracy

Real-time market insights

Our Montel BESS Index is built on insights from over €1 billion of financed battery projects and 1 GW of installed capacity across Europe. Available at the moment for Germany, Netherlands and Belgium.

Our benchmarks are grounded in real trading data, validated by leading developers, investors, and operators.
By combining decades of market knowledge with advanced analytics, Montel delivers benchmarks that reflect how markets actually behave, not just how they should.

Transparency that builds trust

Full transparency. Real comparability.

Every data point in our Montel BESS Index is traceable, reproducible, and fully explained.

Benchmark assumptions - from market share constraints to cycle limits - are visible and adjustable.
This transparency allows asset owners, traders, and financiers to trust what they see and compare on equal terms.

No black-box algorithms. No unrealistic revenue figures. Just clarity and control.

Montel BESS combines decades of market experience, real-time power data and advanced optimisation modelling to simulate how battery assets perform under realistic market conditions.

Our approach is built on the “rolling intrinsic” principle - continuously re-evaluating each market opportunity to reflect how trading, state of charge and capacity constraints interact throughout the day.

Benchmark Models Included

Perfect Foresight Model – Calculates the theoretical upper bound of achievable revenues using historical market prices. Useful for identifying the maximum achievable performance of an asset.
Market Practice Model – Mirrors actual market behaviour and trading constraints to provide a realistic, “revenue-to-beat” baseline.
Continuous Intraday Model – Simulates sub-hourly trading decisions in continuous intraday markets, capturing real-time volatility and liquidity effects.

No two batteries operate under the same conditions. Montel BESS allows you to select from a wide range of configuration parameters so you can benchmark performance against assets that truly match your profile.

Configurable Parameters

Power Capacity: 1 MW / 10 MW / 100 MW
Duration (Energy Capacity): 1 h / 2 h / 4 h
Initial State of Charge: 0 % / 50 % / 100 %
Daily Cycle Limits: 1 / 1.5 / 2 cycles

By combining these variables, Montel BESS generates 80 unique configuration scenarios, each benchmarked across all three models.
Compare how size, duration, or operational constraints influence revenues and identify the setup that best fits your strategy.

Montel BESS is fully integrated within the Montel EnAppSys platform, giving you access to real-time data, historic benchmarks and visual analytics in one environment.

Flexible Access Options

Interactive Dashboards: Explore benchmark revenues, trades, and state-of-charge profiles through intuitive charts and tables.
API Feeds: Pull 15-minute or hourly data directly into your internal systems, forecasting models or bespoke dashboards.
Custom Exports: Download structured data in CSV or JSON for deeper offline analysis.
